I'm not sure specifically as I haven't read this light novel. But generally, a light novel often involves a unique story with interesting characters, settings, and plotlines. It could be about the adventures of the migawari hakushaku character, perhaps in a fantasy or historical setting.
You can try looking for it in specialized bookstores that carry a wide range of light novels. Some large chain bookstores might also have it in their international or niche sections.
The JoJo manga is mainly in black and white. Colored versions exist but are not the norm. Sometimes, colored illustrations are done for promotional purposes or by fans.
I think it's great. The characters are memorable, the plot is full of twists and turns, and the battles are epic. It's a manga that stands out from the crowd.
It depends on personal preferences. Some consider Jojo to be peak fiction for its unique style and engaging storylines. Others may have different opinions.
